Portal Context

The "portal" context identifies a portal within the current hierarchy. Portals can either be used within templates or within layouts, so the parent context of the portal within the hierarchy can vary.

Context Transitions

From within a "portal" context, you can utilize the following set of valid context transitions:

parent

Transitions to the layout context or template context corresponding to the visual element that contains the portal. Example: this.parent NOTE! The "parent" transition can only be utilized a single time, so it is not possible to go upwards two or more levels within the hierarchy.

Target References

The "portal" script context governs the operations that can be applied to portals within templates and layouts. The complete list of target references for portals is presented in the table below.

width	(Left, Right, Number) Accesses the width of the portal. Unless explicitly specified within the XML, the width of a portal is automatically initialized appropriately to the nature of the portal. Setting the width of a table portal triggers immediate re-sizing of all items within the table. Example: result = this.width Example: this.width = 42
height	(Left, Right, Number) Accesses the height of the portal. Unless explicitly specified within the XML, the height of a portal is automatically initialized appropriately to the nature of the portal. Setting the height of a table portal triggers immediate re-sizing of all items within the table. Example: result = this.height Example: this.height = 42
left	(Left, Right, Number) Accesses the position of the left edge of the portal within the containing visual element. Example: result = this.left Example: this.left = 42
top	(Left, Right, Number) Accesses the position of the top edge of the portal within the containing visual element. Example: result = this.top Example: this.top = 42
right	(Right, Number) Returns the position of the right edge of the portal within the containing visual element. Example: result = this.right
bottom	(Right, Number) Returns the position of the bottom edge of the portal within the containing visual element. Example: result = this.bottom
visible	(Left, Right, Number) Controls the visibility of the portal within the containing visual element. A non-zero value indicates the portal is visible and a zero value indicates hidden. Example: result = this.visible Example: this.visible = 1
scrollbar	(Right, Number) Returns the width of a scroller, in pixels. Example: result = this.scrollbar
autotop	(Left, Right, Number) Accesses the position of the top edge of the auto-place region within the containing visual element. Example: result = this.autotop Example: this.autotop = 42
autobottom	(Left, Right, Number) Accesses the position of the bottom edge of the auto-place region within the containing visual element. Example: result = this.autobottom Example: this.autobottom = 420
autoleft	(Left, Right, Number) Accesses the position of the left edge of the auto-place region within the containing visual element. Example: result = this.autoleft Example: this.autoleft = 42
autoright	(Left, Right, Number) Accesses the position of the right edge of the auto-place region within the containing visual element. Example: result = this.autoright Example: this.autoright = 420
autowidth	(Left, Right, Number) Accesses the width of the auto-place region within the containing visual element. Example: result = this.autowidth Example: this.autowidth = 420
autoheight	(Left, Right, Number) Accesses the height of the auto-place region within the containing visual element. Example: result = this.autoheight Example: this.autoheight = 420
autogap	(Left, Right, Number) Accesses the default gap size used when automatically placing elements within the containing visual element. The "autogap" defaults to zero. Example: result = this.autogap Example: this.autogap = 42
autoplace[gap]	(Right, Number) Automatically places the portal within the containing layout, subject to the standard rules for automatic placement. The gap parameter specifies the gap to be used between this portal and the previously placed element. The parameter can be omitted, in which case the established "autogap" is utilized. Automatic placement for portals can only be used within layouts. A value of zero is always returned. Example: perform this.autoplace[42] Example: perform this.autoplace
